Materials - Coggle Diagram

- - - - Some materials allow water or other liquids to filter through
        them. An earthenware jug containing liquid, or a wet cloth
        becomes wet because they're made from permeable
        materials
    - - Some materials don't allow water or other liquids to filter
        through them. For instance, glass is impermeable, so liquids
        stored in bottles don't escape. Plastics and cork are also
        impermeable, or waterproof.
- - - - Some materials conduct electricity, e.g. metals.
    - - Some materials don't conduct electricity, e.g. plastic
        materials and wood.
  - - - The capacity of materials to transmit sound
    - - Some materials don't conduct sound well, e.g. glass, fibre, cork and plastics.
- - - - A physical process is when a substance changes its state,
        for example when a metal melts. The chemical composition
        of the material does not change.
    - - A chemical process is when a substance is transformed into a different substance with different characteristics. The composition of the material changes. For example, petrol derivatives are transformed to create some types of plastic.
- - - - We get raw materials from nature
    - - We process them to make materials.
    - - We make goods with these materials.
- - - - Raw Materials
        Unprocessed
        substances in their
        natural state, classified
        by origin: animal,
        vegetable, or mineral
      - Materials
        Processed raw materials
        ready for making
        products through
        physical or chemical
        processes
      - Properties
        Physical, chemical, and
        ecological
        characteristics that
        determine how materials
        behave and their
        environmental impact
      - Manufactured
        Goods
        Products created by
        humans to satisfy needs
        and improve standard of
        living
    - - The specific properties needed for the product's function
      - The environmental impact and sustainability
      - The availability and cost of raw materials
      - The manufacturing processes required
